A vehicle lighting system in the interior of a vehicle adjusts the radiation area, the brightness, and the color temperature of light depending on the behavior, state, and posture of the passenger, so as to improve passenger convenience and upgrade interior lighting.

A lighting system for a vehicle having at least one lamp device arranged in the region of an interior roof lining of the vehicle. The at least one lamp device is arranged such that a work region is defined by at least a first vehicle row of the vehicle is illuminable by the at least one lamp device. The lighting system comprises a closed-loop lighting system control device which is coupled to a closed-loop vehicle control device of the vehicle and configured to receive vehicle state information from the closed-loop vehicle control device. The lighting system is configured, in a lighting mode of the lighting system, to automatically terminate an illumination of the work region on the basis of received vehicle state information.

A decorative sheet includes, from the front side to the back side, a skin layer, an intermediate layer, a design layer, and a soft layer. Recesses open on at least one of a front surface and a back surface of the design layer. The decorative sheet further includes display regions formed by the recesses. The display regions display a predetermined design on a front surface of the skin layer by light irradiated from the back side. Light is irradiated from the back side to the display regions via the soft layer. Light blocking partition parts of the soft layer are each disposed between two adjacent display regions as seen from the front side, and prevent light to be irradiated to one display region from leaking into the other display region via the soft layer.

This system for detecting the surrounding: conditions of a moving body forcibly changes the state of at least one of a plurality of lighting devices (change from an unlit stats to a lighting state or a blinking state, change in the emission color, or change in the luminance) installed inside the moving body if an object to which attention must be paid during traveling of the moving body is detected in the surroundings of the moving body.

An illumination device projects light in a predetermined illumination pattern on a surface. The illumination device includes a housing having a cavity and an aperture that opens into the cavity. The illumination device further includes a light module operatively attached to the housing for selectively emitting the light into the cavity. Furthermore, the illumination device includes a digital light panel at least partially disposed in the cavity between the light module and the aperture. The digital light panel has at least one opening defining a base pattern configuration corresponding to the predetermined illumination pattern for aligning the light emitted from the light module through the opening into the base pattern configuration and subsequently projecting the light through the aperture onto the surface in the predetermined illumination pattern.

A method for controlling an in-vehicle ambient lamp, performed by a vehicle on-board system, including: receiving an ambient lamp adjustment request from a first terminal device, in which the ambient lamp adjustment request includes ambient light data acquired by the first terminal device; determining a target state of the ambient lamp according to the ambient light data; and controlling the ambient lamp according to the target state.

The present disclosure relates to a method for selectively highlighting visual zones (11, 13, 23, 25, 27, 33) associated with a vehicle (V). A point of origin (0) and a gaze direction of a vehicle occupant are determined and a virtual projection (Pv) plotted corresponding to the gaze of the vehicle occupant. The virtual projection extends from the determined point of origin (O) in a direction of the determined gaze direction. With reference to a three-dimensional model (CMOD) comprising a plurality of pre-defined areas of interest, an intersection of the virtual projection (Pv) with one of the plurality of areas of interest is identified. The method comprises controlling an illumination source (Ln) that is associated with the determined one of said plurality of areas of interest so as to highlight a visual zone (11, 13, 23, 25, 27, 33) associated with the vehicle (V).

In a load control unit, three R, G, and B LED chips that constitute each light source (33a-33d) of reading lamps (25-31) and a connector (35) with a built-in controller are mounted on a circuit board (37) to thereby eliminate the connection of a controller (35b) built into the connector (35) with the built-in controller and the respective light sources (33a-33d) by signal lines. In addition, the controller (35b) and a lighting ECU (43) are connected by a multiplex communication line (39), and the multiplex communication line (39) is routed in pillars (15, 17) of a vehicle (1). Consequently, the number of wires can be reduced compared with when individual wires connected to the respective light sources (33a-33d) are passed through the pillars (15, 17), and thereby making it possible to effectively use limited spaces within the pillars (15, 17) through which many other wires are passed.
